Google Changes Policy on Search Records
"SAN FRANCISCO, March 14 — Web search companies collect records of the searches people conduct, a fact that has long sparked fears among privacy advocates and some Internet users that this valuable personal data could be misused.
Now Google is taking a step to ease those concerns. The company keeps logs of all searches, along with digital identifiers linking them to specific computers and Internet browsers. It said on Wednesday that it would start to make those logs anonymous after 18 to 24 months. Under current practices, the company keeps the logs indefinitely"
